	};
};

Hello lava76.
Can you please provide more details? Such as item examples and send us the crash dumps, if the game crashes.
Regards,
Geez

Turns out the health config was a red herring. I've updated the ticket. Here is a PBO to easily repro the issue:

DayZ_127_Exp_SetHealth_Segfault.pbo847 BDownload

Spawning WoodenCrateTEST should cause the crash (it sets its own health in DeferredInit after spawning).

I have the same issue.
Everything works fine in 1.26, but in 1.27 it doesn't. When I try to install the locker server goes down.

I have the same problems, and the server crashes. The only way out is to wipe the server
